Hi Liggy. I am owner of several Nec-OptiarcÂ´s drives. Last week received the new 7240s. The manufacturing finish seems Lite-On to me... The back of the unit, the trayÂ´s opening way (abrupt), the colour if the inside components seen from the tray (black in NECÂ´s , beige in Lite-On)... Maybe i am wrong...and the chip is from NEC.
